What Is The Hole In The Ozone - Part 2

The video explains the thinning of the ozone layer, primarily caused by CFCs, which release chlorine atoms that disrupt the ozone-oxygen cycle. The Montreal Protocol was established to ban CFCs, replacing them with HFCS, which are less harmful. The ozone layer is expected to recover in 50 to 100 years. The video also clarifies that the ozone hole does not cause global warming and discusses ozone formation in the troposphere, contributing to smog.
